By utilizing a common-to-all centerbeam swiveling support bar, the Swivel Expansion Joint System is able to accommodate large longitudinal displacements (X), extensive transverse displacements (Y), and vertical displacements (Z), as well as vertical rotations of up to 10 degrees. The centerbeams are free to slide on swiveling support bars, which provide equidistant control for centerbeams without the limitations of typical mechanical control devices.
